Seeing through the cosmological bounce: Footprints of the contracting phase and luminosity distance in bouncing models
Aurélien Barrau, Killian Martineau, Flora Moulin
The evolution of the luminosity distance in a contracting universe is studied. It is shown that for quite a lot of natural dynamical evolutions, its behavior is far from trivial an…
A first step towards the inflationary trans-planckian problem treatment in Loop Quantum Cosmology
Killian Martineau, Aurélien Barrau, Julien Grain
For most initial conditions, cosmologically relevant physical modes were trans-planckian at the bounce time, often by many magnitude orders. We improve the usual loop quantum cosmo…
Some Clarifications on the Duration of Inflation in Loop Quantum Cosmology
Boris Bolliet, Aurélien Barrau, Killian Martineau +1
The prediction of a phase of inflation whose number of e-folds is constrained is an important feature of loop quantum cosmology. This work aims at giving some elementary clarificat…
Detailed investigation of the duration of inflation in loop quantum cosmology for a Bianchi-I universe with different inflaton potentials and initial conditions
Killian Martineau, Aurélien Barrau, Susanne Schander
There is a wide consensus on the correct dynamics of the background in loop quantum cosmology. In this article we make a systematic investigation of the duration of inflation by va…
